BATTERY TONGS.

Application filed September 23, 1924. Serial No. 739,276.

Our invention relates to battery tongs adapted to remove the connectors clamped about the terminals of a battery to which the battery leads are secured.

As is well known, after a battery has been used for some timethe terminals become corroded and the connectors become so securely fastened to said terminals that great diliiculty is experienced in removing said connectors whenever it becomes necessary to substitute a new battery or remove the old for the purpose of recharging. With the use of our improved tongs, it is possible in most instances to remove said connectors almost fort.

It is an object of our invention to provide apair of battery tongs in which a pair of relatively movablemembers has associated therewith means for clinching a battery terminal at the top and also at the side, underneath the battery lead is secured, which members when relatively moved will cause said connector to be instantly removed from said terminal.

A further object of our invention is to provide a novel form of battery tongs having a pair of relatively movable members, one of which has associated therewith a stationary jaw and a movable jaw, which movable jaw, when said members are relatively moved is adapted to co-act with said stationary jaw to remove forcibly the electrical connection secured to a battery terminal.

A still further object of our invention is to provide a novel form of battery tongs comprising a pair of relatively movable members, one member of which has associated therewith a stationary element provided with a pair 01 prongs, and also a movable element provided with at least one prong, said prongs, when said members are relatively moved, are adapted to grip the terminal of a. battery to remove forcibly the electrical connection secured to said terminals.

It is also an object of our invention to provide a novel form of battery tongs in which a pair of pivoted members is adapted to be relatively moved so that one of said members may be caused to actuate a movable element associated with the other, to co-ac-t with a stationary element, also associated with said other member, whereinstantly and with scarcely any of connector to which theby when said elements are caused to grip the terminal of a battery, and said members are relatively moved, the electrical conneetor secured to said terminal may be expeditiously and quickly removed.

It is also an object of our invention to provide a pair of tongs in which one member of a pair of relatively movable members is provided with a means for renderingel'i'ective a movable jaw co-acting with a stationary jaw whereby when said mem-' bers are relatively moved said tongs may be caused to remove forcibily the leads from a battery terminal.

A further object ot our invention is to provide a pair of battery tongs comprising a pair of relatively movable members, one of which is provided with a pair of jaws, the other member is provided with means whereby it may be assured that said jaws will forcibly remove the electrical connector secured on a battery terminal.

It is also an object of our invention to provide a pair of battery tongs comprising relatively movable members, one of which has extensions projecting therefrom, one of said extension having associated therewith a means for embracing the terminal of a battery, another of said extensions having a movable means adapted to grip the top of said terminal, said movable means having associated therewith a means for retarding its movement, another of said members also having an extension, which extension has mounted thereon a means, which means, when said members are relatively moved, said movable means is adapted to co-act with said means for en'ibracing said terminal, whereby the electrical connector secured to said terminal may be quickly and expeditiously removed.

It is moreover an object or our invention to provide a novel pair of tongs comprising a pair of pivoted members, one otwhich is equipped with a stationary jaw and a movable jaw, said movable jaw having associated therewith a retarding means, which jaws are also provided with means for clinching an article therebetween, said jaws when said members are relatively moved maybe caused to remove said article from its fixed position.

It is also an object of our invention to provide a novel form of'batter'y tongs which are simple in character, easy and inexpensive to manufacture, du'able, thoroughly practical and efficient in operation, not easy to get out of order, and composed of a minimum number of parts.

Further objects and advantages of our invention will become apparent as the description thereof proceeds.

Describing our invention more in detail, 1 indicates one of the members of our tongs, which member has formed integral therewith, or secured thereto in any preferred manner, a stationary jaw or extension 3, which extension is bifurcated, forming a pair of prongs 5, said bifurcated portion being adapted to embrace the terminal T of a battery BL It is, of course, understood that the shape of the extension 3 as well as the character of the prongs 5 and the cutaway portion forming the same may be any that is in practice found desirable. The member 1 is also provided with an extension l, either integral therewith or secured thereto in any preferred manner.

The extension t has a passage formed therein in any suitable manner, which passage is adapted to receive the pin or movable element 9, which has a spring or retarding means 10 surrounding the same. Said pin or movable element is screw threaded at one end, which end is adapted to receive the cap or cam member 11. The other end of said pin or movable element 9 has formed integral therewith or secured thereto in any preferred manner a head 12, which forms the active member of the movable jaw of our tongs. "On the head 12 may be formed at least one prong G, which may be associated with said head in any manner found desirable, either integral therewith or secured thereto in any way preferred.

The member 1 is preferably, though not nece sarily, flattened, as indicated at 1%, to provide a bearing surface for the other member 53, which is adapted to be pivoted to the member 1 by any conventional form of bolt or screw indicated at 8, the member 2 being also provided with a complementary fiattened portion 14. It is of course understood that any means for pivoting the two members together may be substituted for that shown. It will be clear that the n'iembers l and 2, forming the grasping means by which the tongs are operated, are in practice of considerable length, so that it will be possible for the user to reach down in a motor vehicle in order that the battery and its terminals may be easily reached.

The member 2 is formed with an extension 7, preferably, though not necessarily integral or secured to said member in any preferred manner. In the form shown, the extension 7 is integral with said member and bent at substantially right angles thereto. Said extension has formed thereon a cam or eccentric surface 13, which surface is adapted to coact with the cam member or ap 11 to provide for an eccentric or alternating movement, the pin or movable element 9 being rendered active when the high portion of said cam surface has been reached as the movable members are operated. it will be clear that the shane of the cam su face 13 and the cam member or cap 11 immaterial.

To provide an additional means tor insuring that the electrical connection to the battery terminal is removed therefron'i, especially when said terminal has been so corroded that the connector is securely fastened thereto, 1 either form integral with the extension 7 or-secure thereto in any preferred manner, a projection 2 which may be tapped by a hammer or other implement, a or our tongs have been applied to the battery terminal.

In operation, when it is desired to remove the connector C, to wh'ch is securely fastery lead iv, 1 and 2 are pron arsed underneath and caused to inbrace the tern'iiual prong or proig" of the movabl' then positioned Sill cause the ca. cam member been reached, an osci provided. no pin or wi l now i action or t to grip ti The pro i; 1 move the connector 0 upward, in tantly removing the same, ordinar any 0 ort. Tn stubborn c"- tion 1 may l e gen h a. llil or other implement, insu that the c: neetor be removed. The most stubborn cases will yield instantly to this treatment.
